Packing problems and project scheduling models: An integrated perspective
Hartmann, Sönke - 1999
project scheduling problems. First, the two problem categories are described. This includes a classification of packing … problems as well as of project scheduling concepts. While both problem classes are different with respect to their fields of … special cases of models for project scheduling. The aim is to indicate which project scheduling models can be used to capture …

Optimization of the heterogeneous vehicle routing problem with cross docking logistic system
Al Theeb, Nader; Al-Araidah, Omar; Aljarrah, Manar H. - In: Logistics Research 12 (2019) 1, pp. 1-22
This paper introduces a new mixed integer model to provide efficient distribution plans to route a set of inbound/outbound heterogeneous vehicles in the crossdocking systems that are used to transfer different types of commodities from a manufacturing plant to retail warehouses with allowed...

Using truck-inventory-cost to obtain solutions to multi-period logistics models
Ali, Agha Iqbal; O'Connor, Debra J. - In: International Journal of Production Economics 143 (2013) 1, pp. 144-150
The antithetic opposition between the cost of inventory and the fixed cost of transportation, which leads to multiple alternate near-optima, can be a primary contributor to the computational intractability of the mixed integer program for a two-echelon multi-period distribution system. To...

The Impact of Distribution System Characteristics on Computational Tractability
Agha, Iqbal; O'Connor, Debra J. - Department of Economics and Accounting, College of the … - 2008
Mathematical programming models that seek optimal design and operational plans for distribution systems can be computationally intractable. This paper examines the extent to which distribution configuration and demand characteristics affect the ease of obtaining an optimal solution. Problem...

A mathematical formulation and complexity considerations for the blocks relocation problem
Caserta, Marco; Schwarze, Silvia; Voß, Stefan - In: European Journal of Operational Research 219 (2012) 1, pp. 96-104
The blocks relocation problem (BRP) may be defined as follows: given a set of homogeneous blocks stored in a two-dimensional stock, which relocations are necessary to retrieve the blocks from the stock in a predefined order while minimizing the number of those relocations? In this paper, we...

Cost to produce and deliver cellulosic feedstock to a biorefinery: Switchgrass and forage sorghum
Griffith, Andrew P.; Haque, Mohua; Epplin, Francis M. - In: Applied Energy 127 (2014) C, pp. 44-54
Switchgrass and forage sorghum have both been proposed as potential candidates for high yielding, dedicated energy crops. This research was conducted to determine and compare the costs to produce and deliver switchgrass and forage sorghum biomass under the assumptions that the biomass would be...

Pricing the multiple-choice nested knapsack problem
Drexl, Andreas; Jørnsten, Kurt - 2007
The multiple-choice nested knapsack problem (MCKP) is a generalization of the ordinary knapsack problem, where the set of items is partitioned into classes. The binary choice of selecting an item is replaced by taking exactly one item out of each class of items. Due to the fact that the MCKP is...
